  Among the work at high places, in work with utility poles, a lifeline (lanyard) equipped with a safety belt hook at the end is turned to a vertical pillar and the body is supported by hanging the hook on the D ring attached to the belt. There are many examples, and it is stipulated in the standard that hooks and D-tubes are strong enough to withstand a force of 11.5 kilonewtons. On the other hand, the same belt may be equipped with a carabiner for attaching a tool bag to be used for work, but the carabiner has a shape and size that makes it easy to hook. It may happen that the body is supported by a carabiner. However, the carabiner is usually not strong enough to support the weight, so it can break and cause an accident where an operator falls from a height. In addition to the carabiner, the tool hook body has a hole for passing a cord connecting the tool and the tool hook, and a tool insert for inserting the tool itself. There is a possibility that a safety band hook may be hung on the door, and there is a possibility that a fall accident may occur due to insufficient strength.

  The present invention is to solve such a problem, and provides a tool hook that does not accidentally hang a lanyard hook on a portion having insufficient strength.

  As a means for solving the above-mentioned problem, the tool hook according to claim 1 is capable of inserting a tool between the main body substrate and the surface of the main body substrate provided with a belt loop for passing a waist belt of a safety belt. In this way, the curved plate is fixed to form a cylindrical tool insertion portion.

  In this way, the tool insertion part of the tool hook is made cylindrical so that when the safety belt hook to be hung on the D ring is hooked, the hook opening / closing part does not return to the fixed position, or the hook part is set to D before returning. Since it is necessary to hang deeper than in the case of the ring, the user feels uncomfortable and draws the user's attention, so that it is possible to avoid hooking the tool insertion part by mistake instead of the D ring.

  The tool hook according to claim 2 is the tool hook according to claim 1, wherein the length of the cylindrical tool insertion portion is the maximum value of the distance from the tip of the hook portion of the safety belt hook to the inside of the hook portion. Characterized by longer.

  In this way, because the length of the tool insertion part is longer than the maximum value of the distance from the tip of the collar part of the safety band hook to the inside of the collar part, the opening / closing part of the hook of the safety band does not return to the fixed position. It is possible to avoid hooking the tool insertion part instead of the D ring.

  According to a third aspect of the present invention, in the tool hook according to the first or second aspect, the main body substrate includes a hole through which a safety cord that connects the tool hook and the tool and prevents the tool from dropping is provided. When the smallest distance to another adjacent hole or the edge of the main body substrate is d, the largest one of the circles inscribed in the cross-sectional figure of the hole is the tip of the hook portion of the safety belt hook Is smaller than the largest one of the circles inscribed in the cross-sectional figure at the distance d.

  The hole for the safety cord is originally made to pass the cord for the purpose of connecting the tool hook and the tool with the cord. As in claim 3, the shape and size of the hole and the edge of the substrate are used. By determining the position from each other or the positions of the holes, it becomes impossible to hook the safety band into this hole, so that it is possible to avoid hooking the tool hanging body substrate instead of the D ring.

  The tool hook according to claim 4 is the tool hook according to claim 1, wherein the tool hook has two notches on a surface perpendicular to the main body substrate of the upper opening of the cylindrical tool insertion portion. It is characterized by.

  In this way, by providing a notch in the upper opening of the tool insertion part, the convex part of the outer shape of the tool such as a ratchet wrench meshes with the notch, and the tool body is housed in the cylindrical part, which stabilizes the tool. It can be stored in a safe place, and it is possible to carry tools that do not get in the way of working or moving at high altitudes while avoiding hooking of safety belts in the wrong place, thus increasing safety I can do it.

  The tool hook according to claim 5 is the tool hook according to any one of claims 1 to 3, wherein the tool hook has a notch at a position facing the main body substrate of the upper opening of the cylindrical tool insertion portion. .

  In this way, by providing a notch in the upper opening of the tool insertion part, a tool such as a screwdriver that fits almost entirely in the tool insertion part can be directly touched by the user from the notch part. It becomes easy. Accordingly, it is possible to prevent the hook of the safety belt from being hooked in the wrong place, and at the same time, the tool can be handled smoothly in the work at a high place, so that the safety can be further improved.

  According to a sixth aspect of the present invention, in the tool hook according to the first to fifth aspects, a convex portion is provided in an upper opening of the cylindrical tool insertion portion.

  In this way, by providing a convex part at the upper opening of the tool insertion part, the bulge part of the outer shape of the tool such as a monkey wrench or screwdriver meshes with the convex part, and the tool is stabilized by being stored in the cylindrical part. Can be paid. As a result, it is possible to carry a tool that does not interfere with work or movement at a high place while avoiding hooking of a safety belt in a wrong place, and safety can be further improved.

  The tool hook according to claim 7 is the tool hook according to any one of claims 1 to 6, wherein a plurality of the cylindrical tool insertion portions having different shapes are provided.

  In this way, by providing multiple cylindrical tool insertion parts with different shapes, it is possible to avoid hooking the safety belt in the wrong place, and at the same time, various tools can be used at the same time and at high places. It can be carried without interfering with work and movement, and since the tool can be handled smoothly in work at high places, safety can be further improved.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a perspective view of a tool hook 1 according to an embodiment of the present invention as viewed from the upper right, FIG. 2 is a perspective view of the tool hook 1 as viewed from the lower left, FIG. 3 is a front view, and FIG. 5 is a top view, and FIG. 6 is a cross-sectional view taken along line AA in FIG. This tool hook 1 includes a main body substrate 3, a first tool insertion portion 5 and a second tool insertion portion 7, a first notch 9 and a second notch 10, a convex portion 11, a belt loop 13, and a square hole 15. It has. FIG. 7 is an enlarged view of the range X in FIG. FIG. 8 shows a safety belt hook, which includes a collar portion 19 and an opening / closing portion 21. FIG. 9 is an enlarged view of the range Y in FIG. 10 is a cross-sectional view taken along line BB in FIG.

  The tool hook 1 of the present invention has an elongated belt loop 13 formed by bending both ends of a main body substrate 3 backward and cutting the side surfaces thereof. The size is preferably about 60 mm in length and about 8 to 10 mm in width so as to be suitable for use through a safety belt having a width of 50 mm. However, it is not limited to this depending on the width and thickness of the belt.

  The tool hook 1 of the present invention is provided with two locations, a first tool insertion portion 5 and a second tool insertion portion 7 on the surface of the main body substrate 3 where a tool can be inserted, but the tool insertion portion is one location. But it may be more than three.

  The first tool insertion part 5 and the second tool insertion part 7 form a cylindrical shape, and the cylinder part is long enough not to close the opening / closing part of the hook even if an attempt is made to hang the safety belt hook. For example, about 60 mm is preferable. On the other hand, when the tool insertion portion has a ring shape as seen in the cited documents 1 and 2, a tool can be inserted in the same manner as in the cylindrical shape, but there is a possibility that the safety belt hook is accidentally hooked. In consideration of this, the effect of having a fixed length in the tool insertion portion in the present invention is clear.

  The material of the main body substrate 3, the first tool insertion portion 5, and the second tool insertion portion 7 is not particularly limited, but is a metal (iron, steel, stainless steel, aluminum alloy, etc.) excellent in durability, corrosion resistance, and strength. It is desirable that these welds also have sufficient strength. Specifically, it is desirable that it is 11.5 kilonewtons or more stipulated in safety band hooks and D-ring standards. In Cited Document 2, the tool insertion portion is movable. However, in the present invention, the movable portion on the main body substrate 3 is eliminated, and the first tool insertion portion 5 and the second tool insertion portion 7 are provided as a single piece. The number of parts is reduced by bending the metal plate. This is also effective for maintaining the strength of the tool hook 1 of the present invention.

  The first tool insertion portion 5 is provided with first notches 9 at both ends of the upper opening. As a result, the tool with a bulge at the top, for example, a tool such as a monkey spanner, can be easily caught, and the tool can be stored stably. Further, when the safety cord is connected to the tool, the joint is fixed at the notch location, and the convenience of taking out is improved.

  The second notch 10 in the second tool insertion portion 7 also has the same effect as the first tool insertion portion 5 because the swollen grip portion like a screwdriver fits in the second notch 10. Play. In addition, when the tool is inserted into the tool, the tool can be easily taken out because the user can directly touch the tool with the second notch 10 even if the tool is short in the upper part. Play.

  Since the second tool insertion part 7 is made long in the vertical direction from the substrate so that a monkey wrench or the like can be accommodated, if the convex part 11 is not present, considering that the driver does not slide and stabilize in that direction, The significance of the convex portion 11 is clear.

  The square hole 15 is a hole through which the safety cord passes. As shown in FIG. 7, if the minimum distance from the square hole 15 to another adjacent hole or the edge of the main body substrate 3 is d, the maximum 25 of the circles inscribed in the square hole 15 is taken. Can do. On the other hand, when the cross section of the hook portion 19 is taken at a portion B at a distance d from the tip of the hook hook portion 19 as shown in FIG. 9, as shown in FIG. Can take. When the circle 27 is smaller than the circle 25, the hook 19 can only enter the distance d from the tip into the square hole 15, so that the hook opening / closing portion 21 is closed even if the hook and the main body substrate 3 are engaged. There is no. Therefore, there is an effect that it is possible to avoid hooking the hole of the main body substrate accidentally with the D ring. In this embodiment, it is a square hole, but it may be a circular or other shape that can be hooked with a safety cord and does not hook a safety belt hook.
